BURT D. STEVENS,l OF RIVERSIDE, ILLINOIS, ASSIGNOR TO THE MIEHLE PRINTING PRESS & MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION 0F ILLINOIS.

JOGGER FOR PRINTING-:PRESSES To all whom it may concern.'

Be it known that I, BURT D. STEVENS, a

-eitizen of the United States, residing at Riverside, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Jog ers for Printing-Presses, of which the ollowing is a specification.

My invention relates to printing press nechanism, and refers particularly to joggers used in connection therewith.

It has heretofore been customary, when a printed sheet of paper passes from the delivery mechanism to the receiving table, to bring laterally reciprocating jogger members `in contact with the edges of the sheet, whereby the latter is moved to a predetermined position and the sheets of paper are brought to a more or less even position in a pile. The disadvantage with this mechanism has been that the paper, particularly if it is thin, is very apt to become crumpled when being moved by the jogger members. A further disadvantage lies in the fact that when one printed sheet is moved over another, the ink, which has not had an opportunity to become thoroughly dried, is very apt to smear.`

It is the object of my invention to place the sheets of paper in an even pile, and at the same time to do away with the tendency to crumple the paper and smear t-he ink. I accomplish 'this result by employing currents of air which gently and easily force successive sheets of paper against the guide members located on two sides of the receiving table. The above-mentioned disadvan- .tages of the old4 system of operation are not only avoided in this manner` but the currents of air serve `to promote the rapid drying of theink on the printed sheets. The currents of air preferably come from two sides ofthe receiving table, and may be continuous or intermittent. The jets through which the ai passes may also be stationary or vertica ly reciprocating according to t-he requirements of various classes of work, and the apertures may be of any suitable cross section, the term slots herein being used in a general sense and notI as defining openings of any'particular shape. These and other advantages of `my invention will be more readily understood by reference to the accompanying drawings, which Speccation of Letters Patent.

l; and, Fig. 3 is a vertical longitudinal sec-A tion through the same general type of printing press and receiving table shown in Fig. 1, but illustrating the air jets as being vertically reciprocatin The receiving tile 10 is of the well known type, and is provided with the side guide members 11 and 12, which are ad- Justed in desired positions by means of the brackets 13 having the bolts 14, which operate in the slots 15. These members 11 and 12 have the apertures 11a and 12u to allow the escape of air, in the manner which will later be more Vfully explained. Placed near two edges of the receiving table 10 are they side members 16 and 17, which may be either stationary or adjustable. The pipe 18 is located on two sides of the receiving table 10, and occupies a position parallel to the side members 16 and 17. In each of the latter are the vertical slots 19, each of which is covered on its exterior by a cap 2 0, which communicates through a pipe 21 with the pipe 18. Each of the caps 20 is of such shape that it supplies air to t-he entire length of the corresponding slot 19.

Carried on the brackets 22 of the printing press is the shaft 23, on which are mounted pulleys 24, over which pass the delivery tapes 25. Also carried by the brackets 22 is the transverse fly shaft 26, to which the fly rods 27 are rigidly attached. When the printing press is operated the ily shaft 26 rotates in the well known manner, and de livers successive sheets of paper to the receiving table 10.

The operation of my invention may now be readily understood: The paper which comes from the printing portion of the printing press is delivered to the fly rods 27 by means of the delivery tapes .25. The fly shaft 26 is then rotated by suitable well known mechanism, and delivers the paper to a lposition directly above the receiving table 10. Currents of air are meanwhile coming from the various slots 19 in the lsidemembers 16 and 17, so that the sheet descends on these currents of air and is bodily carried'into posit-ion so that two edges of the sheet are brought into contact with the guide members l1 and 12, through the apertures 11 and 12' of which the air escapes. rihis same operation is repeated as successive sheets of printed paper are delivered from the tly, so that the even pile 28 is gradually formed. The air coming through the slots 19 may dow continuously during the operation oi the press,` or by suitable mechanism its dow may be intermittent and started-only as the sheet of paper is delivered from the dy.

ln Fig. 3 li have shown a slight modification of my invention. Attached to the fly shaft 26 is a crank 29, which is pivotally connected to the link 30, which, in turn, is connected to the rod 31. Carried by the rod 31 is the bracket 32, which supports the air pipe 18 having air nozzles 33. lit'will be evident that when the y shaft A26 is rotated to deliver paper tothe receiving table 10 the link 30 is raised by the action oi the cam 29, and, correspondingly, the bracket 32 is elevated. This causes the pipe 18 to move up wardly, carrying the nozzles 33 up in the slots 34:, so that as the paper is delivered the nozzles 33 are in their highest positions. As the fly moves back into its normal position, shown in the drawings, the nozzles 33 are lowered, andthe paper is thereby gradually allowed to descend as the nozzles are lowered, at the same time the action of the air serving to carry the sheet against the guide members 11 and`12. if the nozzles 33 are directly connected with the pipe 18, as shown in Fig. 3, the entire pipe 18 is reciprocated in a vertical plane, whereas if the nozzles 331 are connected to lrthe pipe by means of derible rubber-'couplings or the like, the nozzles alone may be reciprocated, and the pipe 18 may remain in a stationary position.

1t will be apparent to those skilled in the art that many changes could be made in the detailed construction of the parts which 'i have described without departing from the spirit or scope of my invention. For example, instead oi using a ily, any other suitable paper delivering means could readily be employed.

What i claim is:

1. ln a printing press, the combination of delivery means, a receiving table having a.

pair ot adjustable guide members substantially at right-angles to each other, and a pair of side members parallel to said guide members, each vof said side members having a delivery slot therein, and means for delivering air. through said slots, whereby the sheets ci? paper vsuccessivelyv coming from said delivery means will be directed into contact with said guide members, substantially as described.

2. lin a printing press, the combination of nier/eee delivery means, paper 'receiving means, a guide member on said receiving means means for directing an air )et toward sal guide member, and means for vertically reciprocating said jet directing means as said delivery means is operated, whereby the sheets of paper coming successively from said delivery means will` be brought into contact with said guide member, substantially as described.

3. ln a printing press, the combination of delivery means, a receiving table, a pair of guide members on said receiving table mounted substantially at right-angles withy each other, means tor directing an air jet toward each of said guide members, and means for vertically reciprocating said jetdirecting means as said` delivery means is operated, whereby the sheets of paper coming successively from said delivery means will be directed into contact with said guide members, substantially as described.
